JPG to PNG Converter

The output is a PNG copy at the original pixel dimensions.

PNG is lossless but can be larger than the original JPG, especially for photographs.
HOW IT WORKS

Private, browser-first processing.

ImageShaper processes selected files directly in the browser. Your source image is not uploaded to a conversion server by the tool.

For very large images, browser memory limits vary by phone or computer. Keep the tab open until processing finishes.

PRACTICAL LIMITS

Built for ordinary web images.

  • Inputs are capped at 40 MB.
  • Very large megapixel counts can use substantial browser memory.
  • Quality controls apply to JPEG and WebP outputs.
  • Keep the page open until the output is ready.
FAQ

Before you process.

Does JPG to PNG improve quality?

No. Converting cannot restore detail already lost by JPEG compression.

Why is the PNG bigger?

PNG is lossless and usually less efficient than JPEG for photographs.

Is the conversion local?

Yes. The browser decodes the JPG and creates the PNG on this device.
